I too use my walking foot for all piecing (except of course paper piecing), even the smaller pieces. Yes its a little more difficult to feed, but I still do it. Here are some tips
1) Use a leader
2) Work with your needle in the down position. When its time to start a new piece, lift your presser foot just enough to slide the new piece under the foot. Now slide your piece under the foot all the way forward until it is up against the needle and against the 1/4" guide.
3) Slow your speed down
4) A stiletto helps as well
5) Sometimes with really small pieces (I've done 9 patches with 1" strips) I'll use long pins. I insert the pin so the point is a little more than 1/4" from the edge and will not get under the needle, then I use the long shaft of the pin as a "handle" to help guide/move the fabric (especially when at the end of the piece to make sure it doesn't 'drive' to the left)
6) Make sure the feed dogs on your machine and on the walking foot are kept clean and free of fabric/thread dust.
Hope this helps
